Hi,
In lunar calendars, like the Hebrew one, depending on the year, most of the time you'd have alternating 29, 30 days months. However, it may happen to have two consecutive 29 days months. This means that the two next months are necessarily 30 days each to balance things out. Typically, it should be impossible to have 29 days three times in a row, or 30 days three times in a row. So that is why you end up with 29, 29, 30, 30 or 30, 30, 29, 29, depending on the year.
The number of days in lunar months is generally based on past observations, and it seems that it has been already ruled out at the time that the months would just alternate between 29 and 30 all along, because the cycle is not exactly 29.5 days.
